For example, the mobileterminal 100 can include a plurality of displays that are arranged on asingle face at a predetermined distance or integrated. Otherwise, theplurality of displays can be arranged on different sides.

When the display module 151 and a sensor sensing touch (referred to as atouch sensor hereinafter) form a layered structure, which is referred toas a touch screen hereinafter, the display module 151 can be used as aninput device in addition to an output device. The touch sensor can be inthe form of a touch film, a touch sheet and a touch pad, for example.

The touch sensor can be constructed such that it converts a variation inpressure applied to a specific portion of the display module 151 or avariation in capacitance generated at a specific portion of the displaymodule 151 into an electric input signal. The touch sensor can beconstructed such that it can sense pressure of touch as well as theposition and area of touch.

When touch input is applied to the touch sensor, a signal correspondingto the touch input is transmitted to a touch controller. The touchcontroller processes the signal and transmits data corresponding to theprocessed signal to the controller 180. Accordingly, the controller 180can detect a touched portion of the display 151.

Referring to FIG. 1, the proximity sensor 141 can be located in aninternal region of the mobile terminal, surrounded by the touch screen,or near the touch screen. The proximity sensor senses an objectapproaching a predetermined sensing face or an object located near theproximity sensor using electromagnetic force or infrared rays withouthaving mechanical contact.

The interface 170 receives data from theexternal devices or power and transmits the data or power to theinternal components of the mobile terminal 100 or transmits data of themobile terminal 100 to the external devices.

The interface 170 can include a wired/wireless headset port, an externalcharger port, a wired/wireless data port, a memory card port, a port forconnecting a device having a user identification module, an audio I/Oport, a video I/O port, an earphone port, etc., for example.

An identification module is a chip that stores information forauthenticating the authority to use the mobile terminal 100 and caninclude a user identify module (UIM), a subscriber identify module (SIM)and a universal subscriber identify module (USIM). A device (referred toas an identification device hereinafter) including the identificationmodule can be manufactured in the form of a smart card. Accordingly, theidentification device can be connected to the mobile terminal 100through a card slot included in the interface 170.

So far, with reference to FIG. 1, structure of a mobile terminal 100according to the present invention has been described. In what follows,characteristics of a mobile terminal 100 according to the presentinvention carrying out a memo function will be described in more detail.

FIG. 2 is a flow diagram illustrating a method for generating a memofile for a mobile terminal according to an embodiment of the presentinvention. In response to the user's operation, the controller 180 ofthe mobile terminal 100 activates a handwriting input function employinga touch screen 151 of the mobile terminal 100, S100. According to thepresent invention of this document, the user can perform a touch motionagainst the touch screen 151 by using his or her body part (e.g., afinger), a stylus pen, and the like. Furthermore, the user can perform ahandwriting input motion through the touch screen 151.

If a handwriting input function is activated, the controller 180deactivates the execution screen of a particular application displayedon the touch screen 151, S110. For example, while in the activationstate, a touch on a particular area of the execution screen of aparticular application causes a function corresponding to the particulararea to be performed; however, in the deactivation state, a functioncorresponding to the particular area is not performed even if a touch issensed on the particular area.

Here, a particular application may include an application for operatingthe mobile terminal 100 as well as an application for carrying out aparticular function such as a phone application, a memo application, aweb browsing application, and so on. Therefore, the execution screen ofthe particular application can correspond to an execution screen of anapplication for carrying out a particular function, a lock-screen (whichis an execution screen of an operating application), a waiting screen,and so on.

FIG. 3 illustrates a procedure of a user's activating a handwritinginput function of the mobile terminal 100 on a lock screen according tothe method for generating a memo file illustrated in FIG. 2. FIG. 4 is ascreen of the mobile terminal 100 with a handwriting input functionactivated according to the method for generating a memo file illustratedin FIG. 2.

With reference to FIG. 3, the user, touching a soft key 151Acorresponding to a handwriting input function displayed in an indicatorarea, can activate a handwriting input function employing the touchscreen 151. Though not shown in FIG. 3, the user can also activate ahandwriting input function employing the touch screen 151 by pressing ahardware key included in the mobile terminal 100.

In what follows, with reference to FIG. 4, characteristics found on thescreen 151 of the mobile terminal 100 will be examined when ahandwriting input function is activated. If a handwriting input functionemploying the touch screen 151 is activated, the controller 180decreases a transparency of an execution screen of the particularapplication, thereby changing the execution screen of the particularapplication into a translucent state. Then the user, checking that theexecution screen of the particular application has been changed into atranslucent state, can recognize that the execution screen of theparticular application has been deactivated. It should be noted that thecontroller 180 does not perform a lock-release function for the mobileterminal 100 in the state of FIG. 3 even if the user performs a touchoperation to release lock.

If a handwriting input function employing the touch screen 151 isactivated, the controller 180 can display a message window 151B on thescreen 151, inquiring whether to include an execution screen of theparticular application at the time of creating a memo file. If the usertouches a selection button 151B′ of the message window 151B, thecontroller 180 can generate a memo file by using at least part of theexecution screen of the particular application. A method for generatinga memo file by using an execution screen of a particular applicationwill be described in detail with reference to FIGS. 23 to 38.

Also, if a handwriting input function employing the touch screen 151 isactivated, the controller 180 can display a pop-up window 151C on thescreen 151 of the mobile terminal 100 for a predetermined time, thepop-up window displaying a message that a character or an image can beinput through handwriting since a handwriting input function has beenactivated.

In addition, if a handwriting input function employing the touch screen151 is activated, the controller 180 can display a setting area 151D forselecting a style for a line generated through handwriting input on thescreen 151 of the mobile terminal 100. At this time, the style of a linegenerated through handwriting input can include color, texture,thickness, transparency, and so on; but the scope of the presentinvention is not limited to the above.

It should be noted that a method for deactivating an activatedhandwriting input function can include a method of re-touching a softkey 151A corresponding to a handwriting input function while thehandwriting input function is activated and a method of pressing a homebutton 151E, and a method of pressing a back key; but the scope of thepresent invention is not limited to the above.

As opposed to what are illustrated in FIGS. 3 and 4, if an executionscreen of the particular application is updated according to anexecution procedure, the controller 180 can update an execution screenof the particular application according to the execution procedure ofthe particular application while keeping the execution screen of theparticular application in a deactivation state.

FIG. 5 is a procedure through which an execution screen of an SNSapplication deactivated upon activation of a memo function is updatedaccording to the execution procedure of the SNS application. Withreference to FIG. 5, as new messages are arriving, old messages movesubsequently to a downward direction of a screen. Therefore, the usercan check the execution procedure of an SNS application even while ahandwriting input function is activated.

So far, it has been described with reference to FIGS. 3 to 5 that ahandwriting input function of the mobile terminal 100 according to thepresent invention can be activated in a lock screen and an executionscreen of a particular application. However, the handwriting inputfunction of the mobile terminal 100 according to the present inventioncan be a function included in a memo application.

For example, if a handwriting input function is activated as a memoapplication is performed while an execution screen of the particularapplication is displayed on the touch screen 151, the user, checking theexecution screen of the particular application being updated, may inputhandwriting through the touch screen 151, perform an editing function(e.g., copy, paste, cut, etc.) against the handwriting input, or open amemo file and perform an editing function against the memo file. At thistime, the execution screen of a memo application can be regarded as atransparent or translucent virtual layer being formed on the executionscreen of the particular application and blocking a response of theparticular application according to a touch input. In other words, aslong as the handwriting input function is activated, the controller 180of the mobile terminal 100 can update the execution screen of theparticular application while keeping the execution screen of theparticular application in a deactivation state.

Again, with reference to FIG. 2, if the execution screen of theparticular application is deactivated, the touch screen 151 receiveshandwriting input generated based on a touch input of the user S120.Then the controller 180 converts the received handwriting input into amemo file and store the memo file S130.

FIGS. 6 to 8 illustrate a procedure through which handwriting inputreceived through a touch screen 151 is stored in the form of a memo fileaccording to the method for generating a memo file illustrated in FIG.2. More specifically, FIGS. 6 to 8 illustrate a procedure through whichthe controller 180 of the mobile terminal 100 converts handwriting inputreceived being overlapped on a deactivated lock screen into an imagefile and generates a memo file including the converted image file.

As shown in FIG. 6, the user selects handwriting input 151G displayed onthe screen 151 of the mobile terminal 100. Then the controller, as shownin FIG. 7, displays soft keys 151H1, 151 H2 intended to select storagespace for a memo to be generated on the screen 151 of the mobileterminal 100. A first soft key 151H1 of the soft keys 151H1, 151H2 is asoft key intended to store the memo file to be generated into thestorage space associated with a memo application while a second soft key151H2 is a soft key for storing the memo file to be generated into clipboard.

As shown in FIG. 7, if the user touches the first soft key 151H1, a memofile generated is stored in the storage space associated with the memoapplication. Then, as shown in FIG. 8, the user can check the generatedmemo file by activating a memo application in conjunction with thestored memo file. Referring to FIG. 8, it can be seen that a memo fileincluding an image file 151I converted from handwriting input has beenstored in the storage space associated with the memo application. FIG. 9is a flow diagram illustrating one example of a method for generating amemo file for a mobile terminal according to the present inventionillustrated in FIG. 2. In what follows, the method for generating a memofile will be described with reference to related drawings.

Handwriting input is received through a touch screen 151 while ahandwriting input function is activated S120. If handwriting input isreceived through the touch screen 151, the controller 180 of the mobileterminal 100 determines whether the handwriting input can be convertedto text S131. If it is found that the handwriting input cannot beconverted to text, the controller 180 can convert the handwriting inputinto an image S132 and generate a memo file including the convertedimage and store the memo file into a storage unit 150.

If the controller 180 determines that the handwriting input can beconverted to text, however, the controller 180 displays a pop-up windowfor deciding whether to convert the handwriting input into an image ortext S133. In other words, if the handwriting input can be converted totext, the controller 180 displays a pop-up window for choosing aconversion scheme of the handwriting input. However, if it turns outsuch that conversion of the handwriting input into text is unattainable,the controller 180 does not display a pop-up window for the user'schoosing a conversion scheme on the screen 151 of the mobile terminal100.

Next, the controller 180 determines whether the user makes a choice forconverting the handwriting input into text S134. If the user makes achoice for converting the handwriting input into an image through thepop-up window, the controller 180 converts the handwriting input into animage S132. However, if the user makes a choice for converting thehandwriting input into text, the controller 180 can convert thehandwriting input into text S135 and generate a memo file including theconverted text and stored the memo file in a storage unit 150.

FIG. 9 illustrates a case where the controller 180 displays a pop-upwindow for choosing a conversion scheme of the handwriting input on thescreen 151 in the case that handwriting input can be converted intotext. However, depending on embodiments of the present invention, thecontroller 180 can convert the handwriting input directly into textwithout providing a pop-up window for choosing a conversion scheme ofthe handwriting input.

FIGS. 10 to 11 illustrate a procedure of generating a memo fileincluding text 151K converted from handwriting input 151G according to amethod for generating a memo illustrated in FIG. 9.

Referring to FIG. 10, it can be known that if the handwriting input 151Gcan be converted to text, the controller 180 of the mobile terminal 100displays a pop-up window 151J for choosing a conversion scheme of thehandwriting input on the screen 151. As shown in FIG. 10, while a pop-upwindow 151J is displayed, the user makes a choice to convert thehandwriting input into text through the pop-up window 151J. Then thecontroller 180 converts the handwriting input into text and generates amemo file including converted text and stores the memo file. Then, asshown in FIG. 11, the user can check the memo file including the text151K converted from the handwriting input by activating a memoapplication.

So far, a method for storing handwriting input received through a touchscreen 151 into a memo file has been described with reference to FIGS. 2to 11. The mobile terminal 100 according to the present invention,however, can convert the handwriting input into an image or text andstore temporality the converted handwriting input into a clipboardinstead of storing the handwriting input in a memo file. In what follow,an example of using handwriting input by storing the handwriting inputinto a clipboard will be described with reference to FIGS. 12 to 16.

FIG. 12 is a flow diagram illustrating a method for using handwritinginput for the mobile terminal 100 according to an embodiment of thepresent invention. In what follows, a method for using the handwritinginput will be described with reference to related drawings.

Handwriting input is received through a touch screen 151 while ahandwriting input mode is activated S120. Then, the controller 180 ofthe mobile terminal 100 converts the handwriting input into text and/orimage and stores the converted handwriting input in a clipboard S140.Depending on settings, the text and/or image can be stored automaticallyinto the clipboard or stored into the clipboard according to the user'sselection. A procedure through which the handwriting input is convertedcan be performed in the same manner as or in a way similar to the methoddescribed with reference to FIGS. 2 to 11; therefore, a detaileddescription thereof will be omitted. If the converted text and/or imageis stored in the clipboard, the controller 180 carries out a particularapplication based on the user's operation S150. At this point, it isdesirable for a particular application to be capable of carrying outfunctions of paste, delete, and copy against text, image, and so on.While the particular application is running, the controller 180 receivesa long-touch from the user against an execution screen of the particularapplication S160. Here, the long-touch of the user corresponds to aright mouse click in a computer system.

If a long-touch against an execution screen of the particularapplication is received, the controller 180 displays a pop-up window forpasting an execution screen of the particular application with textand/or image stored in the clipboard S170. Next, if the user's touch isreceived against the pop-up window, the controller 180 performs pastingthe stored text and/or image S180.

In the following, one example of a method for using handwriting inputillustrated in FIG. 12 will be described with reference to FIGS. 13 to16. FIGS. 13 to 16 illustrate a procedure of carrying out a method forusing handwriting input illustrated in FIG. 12.

Referring to FIG. 13, the user touches a second soft key 151H2 whilehandwriting input 151G is displayed on the screen 151. Then, thecontroller 180 converts the handwriting input 151G into text and storesthe converted text into a clipboard.

As shown in FIG. 14, while the converted text is stored in theclipboard, the user carries out a schedule application and makes along-touch against the execution screen of the schedule application.Then, the controller 180, as shown in FIG. 15, displays a pop-up window151M for pasting the text stored in the clipboard to the executionscreen of the schedule application on the execution screen of theschedule application.

Next, as shown in FIG. 15, if the user touches an area of the pop-upwindow corresponding to a paste function, the controller 180 pastes thetext 151K stored in the clipboard to the execution screen of theschedule application as shown in FIG. 16.

FIG. 17 is a flow diagram illustrating another example of a method forgenerating a memo file for the mobile terminal 100 according to thepresent invention illustrated in FIG. 2. More specifically, FIG. 17 is aflow diagram illustrating a method for generating a memo file by usingall of handwriting input received through a touch screen 151 and anexecution screen of a particular application displayed on the touchscreen 151. In what follows, the method for generating a memo file willbe described with reference to related drawings.

While a handwriting input mode is activated, handwriting input isreceived through a touch screen 151, S120. Then the controller 180 ofthe mobile terminal 100 extracts part of the handwriting input which canbe converted into text S190.

Next, the controller 180 converts part of the handwriting inputinconvertible to text into an image S200 whereas the part convertible totext is converted into text or image S210. A procedure of converting thepart of handwriting input convertible to text into text or image can beperformed in the same manner as or in a way similar to the methoddescribed with reference to FIGS. 2 to 11; therefore, a detaileddescription thereof will be omitted.

If conversion of the handwriting input into text and/or image iscompleted, the controller 180 generates a memo file including theconverted text and/or image and stores the generated file S220.

In what follows, examples of the method for generating a memo file willbe described with reference to FIGS. 18 to 22. FIGS. 18 to 22 illustrateprocedures of generating a memo file according to a method forgenerating a memo file illustrated in FIG. 17.

With reference to FIG. 18, the user inputs handwriting to the screen 151of a touch screen 151. Then the controller 180 extracts from thehandwriting those parts convertible to text 151G, 151G1, 151G2 andregards the remaining part of the handwriting as the part 151G3impossible for conversion to text.

FIG. 19 illustrates a case where the controller 180 converts the wholeof handwriting input 151G, 151G1, 151G2, 151G3 into images 151I, 151I1,151I2, 151I3 and generates a memo file based on the images converted.

FIG. 20 illustrates a case where the controller 180 converts only part151G1 of those text convertible handwriting inputs 151G, 151G1, 151G2into text; converts the remaining part 151G2, 151G3 into images;converts part 151G3 of handwriting input inconvertible to text into animage; and generates a memo file based on the above conversion.

Here, the part converted to text from among those text-convertiblehandwriting inputs 151G, 151G1, 151G2 may have been selected by theuser. In other words, the controller 180 can convert at least part 151G1of those convertible to text 151G, 151G1, 151G2 from among thehandwriting input received 151 G, 151 G1, 151G2, 151G3 into textaccording to the user's selection.

FIG. 21 illustrates a case where the controller 180 convertstext-convertible handwriting inputs 151G, 151G1, 151G2 into a pluralityof text group 151K, 151K1, 151K2; converts the part 151G3 inconvertibleto text into an image 151I3; and generates a memo file based on theabove conversion. Also, it can be seen from the FIG. 21 that thecontroller 180 has generated a memo file by taking account of theposition of handwriting.

Comparing FIGS. 21 and 22, the controller 180 may not consider theposition of handwriting input at the time of converting handwritinginput into text and/or image. At this time, as shown in FIG. 22, theuser can selectively move a text group converted by taking the positionof handwriting input into consideration.

In a method for generating a memo file and a method for usinghandwriting input in the mobile terminal 100 according to the presentinvention described above, considered was only the handwriting inputobtained through a touch screen 100 by the user. However, thedescription below with reference to FIGS. 23 to 38 indicates that themobile terminal 100 can perform a function similar to the method forgenerating a memo and the method for using handwriting input by usingboth handwriting input and the execution screen of a particularapplication displayed on a current touch screen 151.

FIG. 23 is a flow diagram illustrating another example of a method forgenerating a memo file for the mobile terminal 100 according to thepresent invention illustrated in FIG. 2. More specifically, FIG. 23 is aflow diagram illustrating a method for generating a memo file by usingboth handwriting input received through a touch screen 151 and anexecution screen of a particular application displayed on a touch screen151. In what follows, a method for generating a memo file will bedescribed with reference to related drawings.

In response to the user's operation, the controller 180 of the mobileterminal 100 activates a handwriting function which uses a touch screen151 of the mobile terminal 100, S100. If a handwriting function isactivated, the controller 180 deactivates the execution screen of aparticular application displayed on a touch screen 151, S110.

After the execution screen of the particular application is deactivated,the touch screen 151 receives handwriting input generated based on theuser's touch input S120. Then, the controller 180 generates a memo fileincluding a capture image of the execution screen of the particularapplication and stores the memo files S230. At this time, thehandwriting input received can be included in the memo file after beingconverted into text or image according to the description provided withreference to FIGS. 2 to 22. In what follows, examples of a method forgenerating a memo file illustrated in FIG. 23 will be described withreference to FIGS. 24 to 29.

FIGS. 24 to 27 illustrate one example of generating a memo fileaccording to a method for generating a memo file illustrated in FIG. 23.

As shown in FIG. 24, if the user touches a soft key 151A correspondingto handwriting input, the controller 180 activates a handwriting inputfunction and deactivates the execution screen 151N of a particularapplication. Next, the controller 180 can display a message window onthe screen 151, inquiring whether to generate a memo file by using theexecution screen 151N of the particular application.

If the user selects a selection button 151B′ of the message window, theselection button 151B′ is displayed as shown in FIG. 25. Then, thecontroller 180 can use both handwriting input received through the touchscreen 151 and the execution screen 151N of the particular applicationfor generating a memo file.

FIG. 25 illustrates that the user provides handwriting 151G′ overlappingthe execution screen of the particular application and touches a firstsoft key 151H1 to store the handwriting. Then, as shown in FIG. 26, thecontroller 180 generates a memo file including both a capture image151N′ of the execution screen of the particular application and theimage 151I′ converted from the handwriting; and stores the memo file.

At this time, the capture image 151N′ of the execution screen of theparticular application and the image 151I′ converted from handwritinginput can be stored as a single combined image; as shown in FIG. 27,they can be included in the memo file while retaining the respectiveindependence.

Referring to FIG. 27, it can be seen that if the capture image 151N′ ofthe execution screen of the particular application and the image 151Fconverted from the handwriting input are independent of each other, theuser can select the image 151I′ converted from the handwriting input andmove the selected image. Though not shown in the figure, the user canperform the function of copy, paste, and so on by selecting the image151I′ converted from the handwriting input. This applies the same to thecapture image 151N′ of the execution screen of the particularapplication.

FIGS. 28 to 29 illustrate another example of a procedure of generating amemo file according to a method for generating a memo file illustratedin FIG. 23.

FIG. 28 illustrates a case where the user inputs handwriting 151Goverlapping the execution screen of the particular application and afirst soft key 151H1 to store the handwriting input. Then, as shown inFIG. 29, the controller 180 generates a memo file including both thecapture image 151N′ of the execution screen of the particularapplication and the text 151K converted from handwriting input; andstores the memo file. At this time, as described with reference to FIGS.26 to 27, the handwriting input 151G can also be incorporated into amemo file in the form of being combined with a capture image 151N′ ofthe execution screen of the particular application or as an imageindependent of the capture image.

FIG. 30 is a flow diagram illustrating one example of a method forgenerating a memo file shown in FIG. 23. In what follows, the method forgenerating a memo file will be described with reference to relateddrawings.

While a handwriting input function is activated, handwriting input isreceived through a touch screen 151, S120. After handwriting isreceived, the controller 180 of the mobile terminal 100 selects part ofan execution screen of a particular application displayed on the touchscreen 151 in response to the user's operation S240.

If part of an execution screen of the particular application isselected, the controller 180 generates a memo file based on a captureimage of part of an execution screen of the particular application andhandwriting input overlapping the part of an execution screen of theparticular application S250. At this time, the handwriting inputoverlapping the part of an execution screen of the particularapplication can be included into the memo file after being convertedinto text and/or image based on whether the handwriting input can beconverted to text.

FIGS. 31 to 32 illustrate a procedure of generating a memo fileincluding a capture image of part of the execution screen of aparticular application according to a method for generating a memo fileillustrated in FIG. 30.

FIG. 31 illustrates a case where the user inputs handwriting 151G′ to anexecution screen 151N of the particular application and selects part ofthe execution screen 151N of the particular application by using a dragmotion and touches a first soft key 151H1 for generating a memo file.

Referring to FIG. 31, it can be seen that the part not selected from theexecution screen of the particular application is processed to beopaque. Therefore, the user can easily recognize the selected part fromthe execution screen 151N of the particular application. Also, referringto FIG. 31, it can be seen that the user can change a selected area bydragging the corner part of the selected area.

As shown in FIG. 32, if the user touches a first soft key 151H1, thecontroller 180 generates a memo file including a capture image 151N″ forthe part selected from an execution screen of the particular area and animage 151I″ converted from the handwriting; and stores the memo file.Also, comparing FIGS. 26 and 32, the memo file illustrated in FIG. 32has such a difference from that of FIG. 26 that the part of handwritinginput not overlapping the selected area from an execution screen of theparticular application has not been reflected for generation of a memofile.

FIG. 33 is a flow diagram illustrating one example of a method forgenerating a memo file illustrated in FIG. 23. In what follows, themethod for generating a memo file will be described with reference torelated drawings.

Handwriting input is received through a touch screen 151 while ahandwriting input function is activated. If handwriting input isreceived, the controller 180 of the mobile terminal 100 selects part ofan execution of a particular application displayed on the touch screen151 in response to the user's operation S240.

If part of the execution screen of the particular application isselected, the controller 180 extracts the area not included in the partof an execution screen of a particular application S260 and determineswhether the handwriting input not included in the selected part of anexecution screen of the particular application can be converted intotext S270.

If handwriting input not included in the part of an execution screen ofa particular application is inconvertible to text, the controller 180performs image conversion for the handwriting input excluding thehandwriting input not included in the part of an execution screen of theparticular application S280.

However, if handwriting input not included in the part of an executionscreen of a particular application is convertible to text, thecontroller 180 converts handwriting input not included in the part of anexecution screen of a particular application into text S290 and includethe converted text in a memo file being generated. In what follows,examples of a method for generating a memo file illustrated in FIG. 33will be described with reference to FIGS. 34 to 37. FIGS. 34 to 35illustrate one example of carrying out a method for generating a memofile shown in FIG. 33.

FIG. 34 illustrates a case where the user selects part of an executionscreen 151N of a particular application while handwriting input 151G′ isdisplayed on a screen of the mobile terminal 100 being overlapped withthe execution screen of the particular application. Then, handwritinginput 151G′ is classified into the portion 151G′1 overlapping theselected part of the execution screen of the particular application andthat 151G′2 not overlapping the selected part of the execution screen ofthe particular application. While the handwriting input 151G′ isclassified accordingly, the user touches a first soft key 151H1 forgenerating a memo file.

Then, referring to FIG. 35, it can be known that the controller 180 ofthe mobile terminal 100 generates a memo file including a capture image151N″ for the selected part of the execution screen of the particularapplication and an image 151I′2 converted from handwriting input 151G′1being overlapped with the selected part of the execution screen of theparticular application; and stores the generated memo file. The aboveindicates that since the portion 151G′2 of handwriting input notoverlapping the selected part of the execution screen of the particularapplication is inconvertible to text, the corresponding portion isexcluded at the time of conversion to image.

FIGS. 36 to 37 illustrate another example of carrying out a method forgenerating a memo file illustrated in FIG. 33.

FIG. 36 illustrates a case where the user selects part of an executionscreen 151N of a particular application while handwriting input 151G′ isdisplayed on a screen of the mobile terminal 100 being overlapped withthe execution screen of the particular application. Referring to FIG.36, the handwriting input 151G does not overlap the selected part of theexecution screen of the particular application. Under the above state,the user touches a first soft key 151H1 to generate a memo file.

Referring to FIG. 37, then, it can be known that the controller 180 ofthe mobile terminal 100 generates a memo file including a capture image151N″ for the selected part of the execution screen of the particularapplication and text 151K converted from handwriting 151G1; and storesthe generated memo file. The above indicates that since the handwritinginput 151G can be converted to text, the handwriting input 151G has beenconverted into text and included in a memo file even though thehandwriting input 151G does not overlap the selected part of theexecution screen of the particular application. Different from theillustration of FIGS. 36 to 37, at the time of generating a memo file,the controller 180 may not consider handwriting input convertible totext, not overlapping the selected part of the execution screen of theparticular application.

FIG. 38 illustrates a procedure of setting a style for handwriting inputin response to a user's operation. More specifically, FIG. 38illustrates a procedure of changing the color of a line displayed on thescreen 151 at the time of the user's handwriting input.

With reference to the setting area 151D illustrated in FIG. 38, it canbe seen that the mobile terminal 100 illustrated in FIG. 38 can displayhandwriting according to the color selected by the user among fourcolors. Also, if the user selects a particular color displayed in thesetting area 151 d, the color of a line displaying handwriting can bechanged accordingly.

Though not shown in the figure, the mobile terminal 100 according to thepresent invention can provide a setting area for selecting thickness,texture, transparency, and the like of the line generated throughhandwriting input.

FIG. 39 is a flow diagram illustrating a method for generating a memofile according to another embodiment of the present invention. Morespecifically, FIG. 39 is a flow diagram illustrating a method forselecting items displayed on the screen 151 of the mobile terminal 100and generating a memo file by using the selected items. In what follows,the method for generating a memo file will be described with referenceto related drawings.

The controller 180 of the mobile terminal 100 displays a plurality ofitems on the screen 151, S300. While the plurality of items aredisplayed on the screen 151, if the user selects a particular item andactivates a memo function S310, the controller 180 deactivates thefunction corresponding to each of the plurality of items S320.

For example, if a particular item displayed on the screen 151 is an itemlinked to a particular web site and a memo function is activated, thecontroller 180 does not perform the operation linking to thepredetermined web site even if the user selects the particular item.This is because the link function of the particular item with a memofunction activated has been deactivated.

If the plurality of items correspond to the items included in anexecution screen of a particular application, the controller 180 canupdate the execution screen (namely, a plurality of items) of theparticular application according to the execution procedure of theparticular application while keeping the execution screen of theparticular application (in other words, a plurality of items) in adeactivated state.

Meanwhile, activation of selection of a particular item and a memofunction can be performed at the same time; or the memo function can beactivated after the particular item is selected. Also, the particularitem can be selected after the memo function is activated.

After selection of a particular item and activation of a memo functionare performed, the controller 180 converts the selected item into imageor text S330 and generates a memo file including the converted image ortext; and stores the generated memo file. As described above, whether toconvert the selected item into a memo file including text or image canbe determined based on the convertibility of the selected item intotext. According to a method for generating a memo file illustrated inFIG. 39, the memo file generated can also be stored into at least one ofstorage space associated with a memo application and a clipboard.

FIGS. 40 to 43 illustrate a procedure of carrying out one example of amethod for generating a memo file illustrated in FIG. 39.

FIG. 40 illustrates a case where the user make a long-touch on adescription part 151Y of a particular product corresponding to an image151X of the particular project from among a plurality of items displayedon a screen, the controller 180 of the mobile terminal 100 selects thedescription part 151Y of the particular product. With reference to FIG.41, it can be known that the description part 151Y of the particularproduct has been selected and the selected part is displayed with a darkcolor.

As shown in FIG. 41, if the user touches a soft key 151A for activatinga memo function while the description part 151Y of the particularproduct has been selected, the controller 180 activates a memo functionand deactivates a function corresponding to each of the plurality ofitems.

As shown in FIG. 42, the controller 180 displays on the screen 151 apop-up window 151J for determining whether to store the description partof the selected particular product into text or image. This is becausethe description part 151Y of the particular product has an attributewhich enables the description part to be converted into text.

FIG. 42 illustrates a case where the user selects the description part151Y of the particular product to be converted into text. As shown inFIG. 43, then the controller 180 converts the description part 151Y ofthe particular product into text and generates a memo file including theconverted text 151Y′.

If handwriting input provided by the user through the touch screen 151is received after a memo function is activated S380, the controller 180searches for an item corresponding to the received handwriting inputfrom among the plurality of items and displays the search result on thetouch screen 151, S390.

If the user selects for a searched item displayed on the touch screen151, the controller 180 converts the selected item into a memo file andstores the memo file S395. As described above, whether to convert theselected item into text and/or image can be determined based onconvertibility of the selected item into text and a generated memo filecan be stored in at least one of storage space associated with a memoapplication and a clipboard.

FIGS. 52 to 57 illustrate a procedure of searching for an item displayedon a touch screen 151 based on handwriting input received through thetouch screen 151 and storing the searched item in the form of a memofile according to a method for generating a memo file illustrated inFIG. 51.

FIG. 52 illustrates a case where the user touches a soft key 151A foractivating a memo function. Then the controller 180 of the mobileterminal 100 activates a memo function and deactivates a functioncorresponding to each of the plurality of items. Next, the user entershandwriting of “stripe” through the touch screen 151 and touches asearch soft key 151P.

Then, the controller 180, as shown in FIG. 53, displays a pop-up window151Q for determining the scope of a search for the contentscorresponding to the received handwriting input on the touch screen 151.

Referring to FIG. 53, the object of contents search corresponding to thereceived handwriting input may be an application running in a currentmobile terminal 100, a storage unit 160 of the mobile terminal 100,worldwide web, and the like. However, the scope of the present inventionis not limited to the object mentioned above. For example, the item canbe searched in other electronic devices including a server of a networkto which the mobile terminal 100 is connected, another mobile terminal,personal computers, and the like.

As shown in FIG. 53, the user selects an application running in acurrent mobile terminal 100 as an object of contents searchcorresponding to the received handwriting. Then, the controller 180, asshown in FIG. 54, searches for an item corresponding to the receivedhandwriting input of ‘stripe’ from among a plurality of items includedin an execution screen of the application and displays the search resulton the touch screen 151. In other words, the touch screen 151 shows asearched item 151R including the received handwriting input of ‘stripe’from the plurality of items.

Different from what is illustrated in FIG. 53, if multiple items aresearched, the controller 180 can display the search result for themultiple items on the touch screen 151. At this time, the controller180, according to an embodiment of the present invention, can collectsearched items and display the items on the touch screen 151. FIG. 55illustrates a case where the user selects an area 151R′ including anitem 151R including the received handwriting input of ‘stripe’ by usinga multi-touch drag and touches a first soft key 151H1 for generating amemo file. Then, the controller 180, as shown in FIG. 56, displays apop-up window 151J for selecting a conversion scheme for handwritinginput on the touch screen 151. Different from what is illustrated inFIG. 55, the user, after an item is searched, can reduce the areaforming the basis for generating a memo file.

FIG. 56 illustrates a case where the user selects an area and uses theselected area 151R′ for storing a memo comprising text and image throughthe pop-up window 151J. Then, the controller 180, as shown in FIG. 57,can store the selected area 151R′ in the form of a memo file comprisinga cushion image 151R′1 and text of ‘yellow stripe’ 151R′2. Though thecorresponding examples are not shown in the figure, as described above,whether to convert the item selected through a method for generating amemo file illustrated in FIG. 52 into text and/or image can bedetermined based on convertibility of the selected item into text; andthe generated memo file can be stored in at least one of storage spaceassociated with a memo application and a clipboard.

According to a method for generating a memo file described withreference to FIGS. 52 to 57 above, the item corresponding to receivedhandwriting input can be an item including characters recognized by thereceived handwriting input. However, the scope of the present inventionis not limited to the above description.

According to an embodiment of the present invention, the itemcorresponding to the received handwriting input can be an item includingmeaning of a recognized character by the received handwriting input. Forexample, if a character string ‘pink’ is recognized from the receivedhandwriting input, the controller 180 can search for an item with a‘pink’ color from among multiple items displayed on a touch screen 151as an item corresponding to the received handwriting input. Also, if acharacter string of ‘stripe’ is recognized from the received handwritinginput, the controller 180 can search for an item with a ‘stripe’ patternfrom among multiple items displayed on a touch screen 151 as an itemcorresponding to the received handwriting input.

According to another embodiment of the present invention, an itemcorresponding to the received handwriting input can be searched by afigure recognized from the received handwriting input. For example, if aheart shape is recognized from the received handwriting input, thecontroller 180 can search for an item with a heart shape as the itemcorresponding to the received handwriting input.

FIG. 58 is a flow diagram illustrating a method for using handwritinginput according to an embodiment of the present invention. In whatfollows, the method for using handwriting input will be described withreference to related drawings.

The controller 180 of the mobile terminal 100 activates a handwritinginput function of a touch screen 151 based on the user's operation S400.If the handwriting input function of the touch screen 151 is activated,the controller 180 can deactivate a particular function corresponding toat least one item displayed in an area intended as a handwriting inputarea. According to an embodiment of the present invention, thehandwriting input area can correspond to the entire touch screen 151 orpart of the touch screen 151.

In other words, when a handwriting input function of the touch screen151 is activated, even if the user touched an item displayed in ahandwriting input area of the touch screen 151, the functioncorresponding to the item touched by the user is not performed. To bemore specific, if an execution icon of a particular application isdisplayed in a handwriting input area of the touch screen 151 and thehandwriting input function of the touch screen 151 is activated, theparticular application is not performed even when the user touches theexecution icon.

At this time, if an item displayed in a handwriting input area of thetouch screen 151 is an item included in an execution screen of aparticular application, the controller 180 can update the item accordingto the execution procedure of the particular application. For example,if the running application is a navigation application, the controller180 can update the execution screen of the navigation applicationaccording to the procedure of guiding a path of the navigationapplication, though a touch function for the execution screen of thenavigation application displayed in the handwriting input area may bedeactivated.

If the execution screen of the navigation application is not displayedin the handwriting input area of the touch screen 151, the controller180 may not deactivate the function corresponding to a touch on theexecution screen of the navigation application. Then, the user of themobile terminal 100 can control the execution of the navigationapplication through a touch motion as well as running a contents searchby using handwriting input.

If handwriting input is received through the touch screen 151 after thehandwriting input function of the touch screen 151 is activated S410,the controller 180 searches for the contents corresponding to thereceived handwriting input and displays the search result on the touchscreen 151, S420. Here, the contents corresponding to the handwritinginput can be searched inside the mobile terminal 100, namely, in thestorage unit 160 of the mobile terminal 100. More specifically, thecontents corresponding to the handwriting can be searched in the storageunit 160 corresponding to the application currently running in themobile terminal 100.

Also, the contents corresponding to the handwriting input can besearched in a different electronic device on a network to which themobile terminal 100 is connected in a wired/wireless manner. In otherwords, the controller 180 can search a server, another mobile terminal,or a PC on a network to which the mobile terminal 100 is connected in awired/wireless manner for the contents corresponding to the receivedhandwriting input. For example, the controller 180 can search theworldwide web to which the mobile terminal 100 is connected in awired/wireless manner for the contents corresponding to the handwritinginput.

If the contents corresponding to the received handwriting input havebeen searched and are displayed on the touch screen 151 and the searchedcontents are selected by the user's touch motion, the controller 180displays a control area for carrying out a predetermined functioncorresponding to the attributes of the search contents S430. Then, thecontroller 180 performs a predetermined function in accordance to theattributes of the searched contents in response to the touch on thecontrol area S440.
